Fine. I'd rather not be the guy, but you pointed out a more sensible alternative. [EDIT] This will take a while to upload, so let me impart some advice: Use gallery-dl. It's defaulted to save post IDs on all compatible sites.
@baconmeh Thank You. My internet isn't that good, so it took like 20 minutes to upload. I used imgbrd-grabber, which let you download from many boorus too. Also I tried to add the dates to the filename for easy organizing and uploading (that's why i posted that in the first post) with "%date:format=yyyy-MM-dd%_%md5%.%ext%", but it didn't work. Only the md5 was saved.
